JE it known that I, ARTHUR M; HAIGHT,

avc'itizen of the United States, residin at Jackson, in the ccunty of Jackson and r tate 6 of Michigan, have inventednew-and useful Improvements in Signal Locks for Automobiles, of which the-following is a speci fication. i v

The object of my presents'ole inventlon is 10 the provision of any efficient lock in'the ignition circuit ofan automobile andjdesigned in one position to complete thecir-v cuit including-the spark plug or plugs and in another position to interrupt the said air- '16"cuit and complete the circuit containing a horn or other audible signal so that when'the usual manually operated switch on the int-'1 strument board is closed the audible signal will besounded and bystanders will be ap- 20 prised of theit'act that an unauthorized at- I temptisxbeing maderto move the automobile;

To the attainment of the foregoing the in- Mvention consists inthe improvement as hereinatter described and definitely claimed.

The-body 1 of fiber or other insulatingmaterial,v and is parts in all the views of the my novel lock is formed of preferably circular in form and provided on its periphery with binding posts 2, 3 and 42; the post 2 being electrically connected with the manual switch, indicated by 5 in Figure 1, the post 3 being similarly connectedwith the horn, indicated by 6 inFigure 1, and the post beingelectrically connected with the spark plugs, indicated by 7 in Figure 1 while'the usual electric button for operating the horn is designated by 7 in Fig. 1.

Extending centrally through the lock body 1 is a metallic sleeve Tit-forming a bearing for a spindle Sonthe forward portion of which-is apreferably knurled handle 9.

Fixed to the spindle "8 at the opposite sideso'f-the body 1, with reference to the hand1e9 is a ratchet disc 1O. Loosely mounted on and revoluble about the sleeve 7", and interposed between ,the rear side of the body 1 and the ratchetedisc 10 are three '11. A; plurality of threaded lugs 11" are adjusted in the threaded openings in reach disc-to suit-the combination desiredfor the through an opening 10 in-the disc 10 and cooperateswith the other lugs to cause the is discs 11 to rotate upon themovementlof the handle 9. A; plurality of circular spacingclements 11" surround the sleeve 7" upon combination discs 11.- Each'disc' 10 is provided with a serles of threaded openings lock. 'The'lu-gin the outer disc 11 extends opposite sides of each disc, A spring 11. is

secured to the'rearside of the body and serves as a stop' for one of thefllugs 11" carried by the inner disc 11. ,These discs 11 be of-the construction and relative arrangement illustrated'or of any other construction and relative'arrangement compatible with the purpose of my'invention and appropriate to the-scheme of the invention that contemplates the working. of a combina tion with view to bringing into coincidemo the enlar ged" V-shaped peripheral notches 12 in the discs 11.

Connected'to the rear s i le of the body 1 and hearing against the peripheries of the two discs 11 nearest the body is a pair of 7 spring pressed shoes 13 the tuncti'oiio't which is 'to prevent toe free novernent of said discs.
